When opening a flap, usually the first entry (~"section") is selected. As an example, open a mail in kmail-mobile. The flap will have the "EMail" section marked (thus "open"). However, touching it ("again") is necessary to view the content, like the "Reply" action etc. Observed in 4:4.5~20100912.1174548-1maemo1.1173569 .
